Forgotten Island opened with an estimated $12.8 million in US and Canadian theaters from September 25 to 27. That put the DreamWorks Animation film in fifth place for the weekend, even though opening-night audiences gave it an A CinemaScore.

The numbers tell different parts of the story. The CinemaScore grade comes from people who bought tickets and saw the movie. The box-office total shows how many people chose it in a crowded weekend. A strong grade does not erase a modest opening, but it gives the film a chance to benefit from fans recommending it to friends.

How did it compare with the other releases?

Box Office Mojo lists Forgotten Island in 3,548 theaters, more than the other new films near it on the chart. Brad Pitt’s Heart of the Beast opened in third with an estimated $20 million. Robert Pattinson’s Primetime was close behind at $19.2 million. The Avengers: Endgame Encore re-release took first with $26 million, followed by Resident Evil at $23.3 million.

That left Forgotten Island behind four films aimed mostly at older viewers. The $12.8 million figure is an opening-weekend estimate, so reported totals may change as final receipts arrive. Its first US weekend is only the beginning of its theatrical run, not a final box-office result.

What are audiences responding to?

The film follows Jo and Raissa, two friends who are about to go separate ways after high school. A portal takes them to Nakali, an island inspired by Filipino folklore. Getting home may cost them the memories of their friendship. H.E.R. voices Jo, Liza Soberano voices Raissa, and Dave Franco voices a creature called Raww.

CinemaScore’s A grade suggests the people polled on opening night liked what they saw. That does not tell us how many new viewers will go next weekend. It does explain why this opening is worth watching closely: the movie has positive audience feedback, but ticket sales have not yet matched it.

What happens next?

The next two weekends will show whether families keep coming to the film or whether the busy release schedule limits it. The Numbers lists roughly $20.6 million worldwide so far, including markets where it opened before the US. That number will keep changing as more countries report results. Forgotten Island remains in theaters; Universal has not announced a streaming date.
